What Causes Increased Yawning?

Sleep deprivation can cause yawning
Detailed Answer:
Hi,
I went through you query and can understand your concern regarding increased yawning.
Your increased yawning is most probably due to the fact that you are not able to sleep adequately at night. Insufficient sleep is the most common cause of yawning and is our brains way of telling us that we need to sleep a bit more to complete the body's need. Its is not due to excessive carbon dioxide in your body.
You having sinus congestion might have been interfering with your ability to sleep. You need to meet your physician and get it treated accordingly.
I do hope that I was able to answer your query. Please do let me know if you have any further queries. I will be glad to help.
Best wishes,
Dr. Sunil Gupta
